On this date in 1962, Georges Kageorgis* was shot at Usumbura (now Bujumbura) for assassinating the charismatic national figure seemingly destined to lead the country into its postcolonial age.

“It was a bit like what could have happened in South Africa if Nelson Mandela was murdered before assuming the presidency in 1994,” said one pol later.

A prince, a pro-independence nationalist, a Tutsi who had married a Hutu and spurned a tribal leadership position lest he cast too sectarian a profile, Louis Rwagasore became prime minister in the fall of 1961 on the strength of his party‘s comprehensive electoral victory.

With the murdered prince went ethnic cohesion; the bloody Kamenge riots of January 1962 presaged worse to come as leadership in the Rwagasore-less party collapsed. Ethnic conflict sharpened through the 1960’s, with a Tutsi-dominated dictatorship ultimately gaining control of the country and setting the stage for intermittent massacres (two classed as genocides) that haunt Burundi to this day and form part of the context for the Rwandan genocide.

Rwagasore Day — October 13, the anniversary of the prince’s assassination — is still observed in Burundi. Kageorgis’s execution date is notable for other reasons: it was the last day before Belgian authority in Ruanda-Urundi officially ended.
